Characteristics of different positions of automotive wiring harnesses

In the complex system of the automobile, the wiring harness plays a crucial role. They are not only the physical bridge connecting the various electronic components, but also the key to ensuring the safety and performance of the car.

Today, we will have an in-depth understanding of the characteristics and technical requirements of the wiring harness in different positions of the car.

Harness the plane layout of the car body

1. Side airbag wiring harness

The wire harness of the side airbag is the core part of the automobile safety system. They must be extremely reliable and responsive in order to quickly activate the airbags and protect passengers in the event of a crash.

Technical requirements include:

Heat resistance: The wire harness material must be able to withstand high temperatures to ensure stability when working near the engine bay.

Anti-interference: The wire harness design needs to reduce electromagnetic interference and ensure clear signal transmission.

2. Door Cable Assembly for Car

The door wire harness is responsible for connecting the electrical equipment on the door, such as window lifters, door locks, etc.

Their characteristics and requirements are:

Wear resistance: Frequent door opening and closing operations require high wear resistance of wire harness materials.

Flexibility: The harness should be designed to adapt to the movement of the door and not be damaged by bending.

3. Rear cable harness

The rear wiring harness connects the lighting and signaling systems at the rear of the vehicle.

Its technical requirements include:

Water resistance: Since the rear body wire harness can be exposed to bad weather, it needs to have good water resistance.

Chemical resistance: The wire harness material must be resistant to chemical attack, such as cleaning agents and fuel.

4. Front Wire Harness For Car

The wiring harness is the key to connecting the electrical equipment in the front of the vehicle, such as headlights, turn signals, etc.

Its technical features are:

Temperature resistance: The front harness must be able to withstand the high temperature environment of the engine compartment.

Vibration resistance: Due to the vibration of the vehicle when driving, the harness needs to have good vibration resistance.

5. Roof cord

Roof cable harness connects roof lighting and trim equipment.

Technical requirements include:

Concealment: The wiring harness design should be hidden as far as possible, without affecting the interior beauty of the vehicle.

Lightweight: In order not to increase the weight of the car, the wiring harness material needs to be lightweight.

6. Engine wire harness

Engine wiring harness is one of the most complex and critical wiring harnesses in the automobile. It connects multiple sensors and control units of the engine.

Technical requirements are:

High temperature resistance: must be able to withstand the high temperature generated by the engine.

High reliability: The wiring harness connection must be very stable to ensure the accurate operation of the engine control system.

7. Main Wire Harness

The main cable harness is the core harness that connects the main electrical system of the vehicle.

Its characteristics and requirements are:

High load capacity: The main beam must be able to withstand high current loads.

Safety: The design must meet strict safety standards to prevent short circuits and fire.

8. Fuel tank Cable

The fuel tank wiring harness is connected to the fuel system and is responsible for the delivery of fuel.

Its technical requirements include:

Explosion-proof: The wiring harness material should have explosion-proof characteristics to prevent the danger of fuel leakage.

Corrosion resistance: The wire harness must be able to resist chemical corrosion of oil products.

9. Dashboard cable assembly

The dashboard cable harness connects various indicators and control buttons on the dashboard.

Technical requirements are:

Accuracy: The wire harness needs to ensure the accuracy of the dashboard display.

Durability: Due to frequent use, the harness needs to be very durable.

The design and manufacture of automotive wiring harnesses is a highly specialized field, and every detail is related to the performance and safety of the vehicle.

With the development of automotive technology, the design of wiring harnesses is also evolving to meet higher performance requirements and more stringent safety standards. Next time you're sitting in your car, think about these invisible wiring harnesses that are the link between car safety and technological progress.
